An apparatus and method for transmitting data of vehicle communication (V2X) services and a communication system. The apparatus includes: a first generating unit configured in a media access control (MAC) layer of the terminal equipment and configured to generate at least one protocol data unit (PDU) in a mode identical to a transmission mode to which a service data unit (SDU) contained in a PDU corresponds; and a first transmitting unit configured in the MAC layer and configured to transmit the PDU to a physical layer of the terminal equipment, and notify the transmission mode to which the PDU corresponds to the physical layer. This disclosure facilitates the physical layer to transmit data in a corresponding transmission mode. The terminal equipment may determine the transmission mode or set the transmission mode according to the indication information, and layers of the terminal equipment perform corresponding processing.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The apparatus according to claim 1, wherein the transmission mode comprises unicast, or groupcast, or broadcast.
3. The apparatus according to claim 1, wherein the processor circuitry notifies the transmission modes to the a network device.
4. The apparatus according to claim 3, wherein the processor circuitry notifies the transmission modes to the network device via a sidelink UE information radio resource control (RRC) message, or a sidelink buffer status report (BSR), or a scheduling request (SR).
5. The apparatus according to claim 1, wherein the indication information provided by the network device of a core network is used to configure transmission modes which data packets on a sidelink or the Qos flows correspond to.
6. The apparatus according to claim 1, wherein the indication information provided by the network device of an access network is used to configure transmission modes which radio link control (RLC) channels or logical channels correspond to.
7. The apparatus according to claim 1, wherein the indication information provided by the network device of an access network contains transmission modes to which scheduled sidelink data correspond.
9. The apparatus according to claim 8, wherein the indication information is used to configure the transmission mode for a sidelink DRB.
